问题 I'm using reportlab to convert some big library (plain text in Russian) into pdf format. When the original file is small enough (say, about 10-50 kB), it works fine. But if I'm trying to convert big texts (above 500kB) it takes lot of time to reportlab to proceed. Does anyone knows what could be the problem? BYTES_TO_READ = 10000 def go(text): doc = SimpleDocTemplate("output.pdf") Story = [Spacer(1, 2*inch)] style = styles["Normal"] p = Paragraph(text, style) Story.append(p) doc.build(Story)

I now put it in Django views, and wondering
